"JSF Good!" Says Rick Hightower
If you have not looked into Spring yet, it is time. Here is why you should!
Grady Booch once said that the great thing about objects is that they can be
replaced. The great thing about Spring is it helps you replace them. With
Spring, you simply inject collaborating objects called dependencies using
JavaBeans properties and configuration files. Then it's easy enough to switch
out collaborating objects when you need to. Spring allows you to dynamically
add services to objects called aspects. This is similar to the Decorator
Design pattern, but does not require you to recompile your code base to apply
these services. This allows you to replace objects with objects that enhance
The ability to inject collaborating objects is often called IoC (inversion of
control). Thus, Spring is an IoC container. If you follow the latest
The past three articles in this series have highlighted the strengths of
scripting languages. They're interactive and dynamic, and allow you to
experiment, debug and prototype solutions quickly. However, the most common
response when I speak to die-hard Java fanatics is, "Yeah, but I'll have to
learn another language and I already know Java" (I consider myself a die-hard
Java fanatic to a degree).
To be honest, this is a barrier that most won't cross. But what if you could
have the best of both worlds? What if you could have your cake and eat it
Well, in a sense you can. Y... (more)

How can Java classes be used as scriptable components? DCOM, like CORBA,
provides both static and dynamic invocation of objects. DCOM uses type
library to provide metadata to do the dynamic invocation and introspection
similar to CORBA's interface repository or Java's introspection mechanism.
IDispatch, a standard COM interface that supports Automation (late binding),
is great for scripting languages such as Perl, Python, VBScript, JScript and
so on. The Microsoft JVM implements IDispatch automatically for... (more)
Interview...with Mike Cowlishaw
Creator of NetRexx
R. Hightower: Have you considered an open- source license?
M. Cowlishaw: Until recently the licensing issues seemed something of a
minefield with so many different ideas on what open source should be. Also,
my translator/compiler is very much a research scaffolding (for example, it
has hooks, which look like dead code, for multiple input syntaxes). At the
moment I'm (finally) implementing the interpreter pathways, which is very
much a work in progress; this sort of thing is much easier to do when only
one person is working on the ... (more)
Time is a brutal enemy of youth and exuberance. Time makes cynics of us all.
Time is the universal truth serum that reveals all authenticity. Time will
tell, but the announcement yesterday by Google may change the faces of AJAX
development, strike that, Google's announcement may change web development
for evermore. This cynic heard an announcement yesterday that changed his
viewpoint and beliefs on the future of web development.
Certainly, in the recent past, the chances of doing an entire application in
AJAX seemed remote for the vast sea of developers. The thought of writing a
